Application filed July 14, 1925; Y seriaino. 43,448.]

My invention relates to improvements in toy cranes.

other object of my invention is to provide a simple and convenient meansof operating edges of the bucket sections are drawn upv the device. Anembodiment of the prepared form of my invention is shown in theaccompanying drawings, in which v Figure 1 is an elevation of thedevice, Figure 2 is a sect-ion of the same on the line 22 in Figure 1with the truck and base removed and a Figure 3 is a detail section onthe line 33 in Figure 2.

Similar characters of reference refer to similar parts throughout theseveral views. My improved device includes a truck 1 havingtractionwheels 2, 2- and a cab ,3 car: ried on a rotatable base 4. 4

In the cab 3 is mounted a boom 5, provided at its base with a carrier 6having a toothed sector 7 engaginga worm gear 8 Theboom 5 is preferablyof sheet metal 'and'is secured to the carrier 6 by means of a lug 11. av

A shaft 12 extends through the. cab 3 and carries the lower end of theboom 5 and its carrier 6.

A crank section 13 of the shaft 12 carries a chain or cable 14 whichextends therefrom over the boom 5 and 15 secured to a sectlonal bucket15 by means of divided strands 16 and 17. a The bucket 15 is of twosections hinge at their adjacent upper edges and having.

arms 18 and 19 extending. inwardly from their outer rims so that whenthe bucket is supported to the arms 18" and 19 the sections will bebrought together and the bucket I closed and when supported, at theirouter edges by the strands 16 and 17 of the cable 1 1 the sections willbe spread and the bucket will be open. t

The bucket 15 is normally carried-by a cable 20 passing over a pulley'21 at the end of the boom 5v and attached to the free ends of the arms18 and 19 whereby the An object of my invention isv to provide a noveland 1nstruct1ve toy. An-

A supporting ear 12- bucket is normally closed andmay be elevated andlowered withthe boom 5. I

When it is desired to open the bucket 15' andthe bucket openedl The boom5 with the bucket 15 carried thereby is elevated and lowered by the wormgear 8 operated by the shaft 10 and turns with the cab 3 on the swivelbase 1.

In operation the boom is lowered by means of the crank 11 and the bucketis opened by applyingtension to the chain 14. The tension on the chain14: is released and the boom is elevated thus drawmg the sect-ions ofthe bucket together by the cable 20 and the arms 18 and 19 whereby sandor other material on which the bucket rests will be scooped up by thebucket.

shaft 10, the worm gear 8 and the carrier 6 and may be turned about withthe cab 3 on its swivel base 4. i

, When it is desired to open the bucket 15 and discharge the load,tension is applied to the chain 1 1 by the crank shaft 12 as aboveexplained and the operation may be repeated as desired.

Having thus described my invention, what I claim is:

1. toy crane of sheet material comprising a truck, a cab rotatablymounted on said truck, a supporting frame mounted in said cab, a shaftjournaled in said frame,

a worm wheel fixed on said shaft, a boom,-

cab, a crank shaft journaled in said cab,

a boom journaled on said shaft, a bucket supported in fixed relation tosaid boom and having two parts pivoted together, means connecting saidcrank shaft and said parts whereby movement of said crank shaft willmove the parts of said bucket relative to one another, a frame fixed insaid cab, a lug in said cab, a second crank shaft journaled in said lugand said frame, a Worm Wheel fixed on said second crank shaft, asectorplate fixed 011 said boom, and teeth on said plate in engagementwith said worm wheel where by movement of said second crank will movesaid boom.

3. In a sheet metal toy the combination of acah havingside walls, ashaft journaled in the side walls at the base thereof, a sector platejournaled on said shaft, said plate being adjacent and parallel to oneof said side walls, a frame fixed to said last mentioned side wall aboveand adjacent said plate, teeth on said plate, a crank shaft in saidframe, a worm wheel fixed to said crank shaft, said worm wheel being inoperative contact with the teeth on said sector whereby movement of saidshaft will move said sector plate.

In testimony whereof, I have signed my name to this specification, this13th day of J uly, 1925.

THOMAS RAYMOND ARDEN.
